It is a very interesting exhibit. The (non-working) prototype of the CPU card is often sitting on top of the uVax that controlls the effects, (Off to the side behind the RAM, in front of the nerd theater.) One interesting challenge is to find all of the bugs in the system. I found a few, and in talking with the designer, discovered some more... /mike (Bug list follows. I am sure there are more :-) Three-legged TO-92 diode (D6 or D9) on the video board. (Though it could be a voltage reference for the DAC...) 80376 on the motherboard. (The prototype used it as a placeholder, since it was the right package to represent an undeveloped ASIC, and the exhibit makers precisely copied the chip number onto the floor. Too many pins on the '486. The green wire in the plug/outled explanation picture is the *hot* lead. A VCC to ground short. \|/ Michael L.
